We have implemented the calculation of the x-ray-absorption cross section for left- and right-circularly polarized x-ray beams within the local-density approximation by means of our all-electron full-relativistic and spin-polarized full-potential linear muffin-tin orbital method. We show that the L{sub 2,3} circular magnetic x-ray dichroism of Fe, Fe{sub 3}N, and Fe{sub 4}N compounds scales to a single curve when divided by the local magnetic moment. Sum rules determine the spin and orbital magnetic moment of iron atoms in these ordered iron nitrides. {copyright} {ital 1998} {ital The American Physical Society}
